so today i was driving to work adn basically lost my brakes. i had to pump them up bout three times so i would be able to stop other wise it would go to the floor and take forever to stop. i got home adn filled the brake resivoir back up cause it was almost gone adn it still does it. i am wonderign if it is brake booster or master cylinder. i dont have much experience with brakes so what do you guys think?
